Beit known that we, J OsEPH N. LONG To a/ZZ whom it may concern:

and

JOHN MOGAFFREY, citizens of the United States, residing at Le Claire, in the county of Scott and State'of Iowa, have invented'a new and useful Improvement' in the Bearing and Support forRudder-Stocks upon Vessels, of

which the followingis a specification.

,. Our invention relates to improvements in bearings and supports for rudder-stocks upon vessels, and the objects are to furnish side supportsr and bearings which willmaterially reduce friction upon the stock in moving the n rudder.

In vessels, particularly steamboats, the rudpasses up through the rake of the boat and through the-main deck at thestern.

Our invention consists i'n having a tube secured through the rake of the boat to its main deck, through which the rudder-stock passes,

which tube has metallic balls, against which the lateral pressure of the stock is exerted,

main deck, with the rudderstock insertedV and represented as cut off at the top of said tube. Fig. 2 isa top view of the rudder-stock represented as out off just above the draw.

band. Fig. 3 is a top View of the rudderstock and tube cutoff just above the balls G; and Fig. 4 is, a vertical sectional view of the tube, rudder-stock, and balls.

Similar letters refer tosimilar parts throu out the several views.

Ais the rudder-stock, composed of an iron tube, at the bottom of which the rudderis to be attached, and at the top of which is to be the same. Neither the rudder or arm is shown in the drawings, because the construction of the same is lwell known; `nor `is the entire length of the rudder stock shown. If desired, the rudder stock may be constructed of a shaft, instead of a tube, or maybe of wood, instead of iron, when a shaft is used.

l E is a tube, which is vertically secured and extends from the rake to the main deck at the sternof the boat.. In the drawings we have l notlillustrated the stern of` a boat, because the different' varieties of construction are well known.

The rudder-stock Ars inserted intatte' tube E, and at d a collar `is shrunkfaround with a complete circle of steel balls, G, of x' suitable size, resting on the top of collar d and against the inner surface of said tube and y .Outerv surface` of said rudder-stock.l At` the top of tube Eis shrunk around it collar, f, which is sufficiently wide to extend a suitable distance above the top of said tube.y The space s' I between the inner surface of rcollar f above the tube and the outer surfaceof the rudder-stockk is lled with a vcomplete circle of steel balls,

H, of suitable size, resting on top of said tube.l

A washer, c,- is .passedcover and around said Y rudder-stock, so its under surface rests -upon` f the top of balls G, and a draw-band, b, is

passed 'around said rudder-stock andsecured` vby the screw-bolt tand nut j, so as vtokeepr .f

washer c in position and vprevent rudderstock A from dropping downpthrough the tubeV rl`he balls G and H may, 4if desired, be con-f.-

structed out of any other rmetallic substance besides steel, and in place-of the draw-bandeb' a collar maybe used, rudderstock.,

' In operation, when turning or rotating the `rudder-stock,lits weight, by means of washer kc, Willbe thrown upon the balls H, whileitsV lateral pressure is substantially'againstv the riveted or bolted to ther i i sides of balls H and G, and said balls will'roll,

and thus diminish friction and materially assistto makethemanipulation of therudder more easy thanby the methods heretofore in use. x

f Having described our invention, what we claim as new, and desire vto secure by Letters Patent, is`

A rudder-stock forlavessel, havingl its v weight vertically sustained by movable metallic balls upon the top of a tube through- Y IOO pressureagainst movable metallic balls at thetop and bottom of said tube,^subs tantially which it is vertically inserted, and its laterall as described. y v JOSEPH N. LONG.
